Abstract: Cavitation damage theories since 1919 are cited and discussed; non-dimensional number, called cavitation damage number, is proposed, based on concept of dynamic indentations produced by short range shock waves due to collapse of cavitation bubbles; results of experiments show that it is possible to predict eroded length, breadth, and area if geometry of cavitating body and value of cavitation parameter are known.

Subject Headings: Cavitation | Shock waves | Erosion | Geometrics | Parameters (statistics)
